SPINDLE i Application filed December 31,` 1926. `Serial No. 158,343.

This invention relates to spindles of the type used in spinning and twisting tramesv and particularly to spindles of the. type in which the Spindle is provided with a ball and socket bearing` whose members are tric`` tionally engaged by a spring under a substantial initial compression, and which spindle is stepped at its lower end in a bearing member carried by the spindle bolster which vis located in an oil well Vformed in the bolster housing.

The present invention has for its object to provide a simple and e'flicient construction slidable in the bolster housing and bearing against the ball member. Y

rMeans are provided for initially compressing the spring and for retaining it in the bolster housing under such compression.-

The ball member is preferably provided with an opening extended through it for the passage of oil to the concaved surface of the socket member, Jfor lubricating the ball and socket bearing.

vThese and other Vfeatures of this invention will be pointed out in the claimsat the end of this specification.

Thedrawing represents in verticalcentral Ainitial compression Vby a suitable tool, not

section a spindle embodying this invention. Reterrngto the drawing a represents the bolster housing provided with a base 8, below which is extended a tubular lower portion' 10 oit substantial length, and above which is extended a tubular upper portion 12 open at itsupper end. o v

The base '8 is designed to rest upon the spindle or ladder. rail of a spinningand twisting frame, not shown,'and is secured theretoby a nut, not shown, which engages a threadedportion of the lower portion 10.

The lower portion 10 is made ot substantial length and' is closed at its bottom to form oil. 13 into which is extended the lower end of a bolster 14 for the spindle blade 15, which is stepped at its lower end in a bearing member 16 located in the lower end of the bolster and secured thereto by a pin 17 or otherwise. i v The bolster 14 is provided with an opening 18 for the passage into it of oil in the oil well. Y

The bolster, housing a is provided atits upper end with a bore or chamber 20 ofy larger diameter than the bore 21 of the main` portioniof the bolster housing, and the inner wall of the bore 21 adjacentthe yenlarged bore or chamber 20 has formed in it a substantially 'semi-Spherical shaped concavity 22, which forms a socket member for a ball and socket bearing for the spindle bolster 111-, theball member 23 of Vwhich bearingfis alixed to orvformed on the bolster 14 and yextends upwardly into the chamber 20. i

The spindle vbolster 14 is providedv with an extension 24; forming a cylindrical bearing member for thespindle blad`e-1`5 within the bolster housing. i

The ball member 23 has cO-o'peratingr with it a sleeve' 25 slidable inthe chamber-Q0 and provided with an inwardly extended bottom flange 26'upon which rests the lower end of 4a helical spring 27, which `is placed under an initial compression sufliciently heavy to force the ball member 23 into engagement with its socket member 22 and tomaintain it against tilting movement with relation to Said socket member under normal conditions of use, but

Vwhichpermits the' spindle bolster and its spindle to oscillate under abnormal eondi-- tions of use-as will be described.`

The Spring 27 is placed under the desired shown, in the hand of the operator, which is pressed, againsta washer 30 located in the chamber 20 and retained therein in any suit- 'able manner as by a split ring 31 which is stdistantialljf" fiat upper surface 35 and y Cir vsleeve and the oil well.

annular flange -or lip 36, which projects slightlj7 above the which the sleeve spring 27.

25 is forced by the The ball member 23V provided with plurality of openings 38 extendedv through surface and against it from its substantially flat upperA surface;r`

35 to its curved lower surface, for the pasy sage of oil from within the sleeve 25 downY to the contacting surfaces ofthe ballfandf socket members to etlicientlj,Y lubricate the latter.' 'I f l Thel'washer 80 is litted closely on the spindle blade and serves to arrest upward movement of the oil from the oil well along the spindle blade` and causeV it to pass into the sleeve 25v from which it is returned vto the oil well through the openings 38 in the ball member 23, which openings are of such size and so'arranged as to directly communicate-r for a portion of their width?,fwith the its upper end and swings withlv the ball mem-v ber asacenter under the influence of an unbalanced load. l

It will alsobe observedY that thevbolster and its coi-operating p arts are insertibleinto and removable y from v the y bolster threu'gh the upper end thereof.

rWhat is claimed is: i

l. In a spindle, in combination, a bolster ,i housing, openyatitsupper end and closed at its lower end to'form an oil well and having its inner wall providedvwith a concavityformin'g a socket member opening up-` wardly, a bolster :forjthe spindle :blade pro.-

berand witliinsaidsleeve 'and co-operatingy withthe latter toy .move it in. the lhousing in' the direction iof the length thereof and effect afdirect lthrust ofthe ball member against its socket member, and'means for initially compressing gsaidf, springl and for -retaining'it in its initially. compressed conthe ball'member, but'the amount of pressiire-v 'used-Twill' vai;7 with the "typeof spindle a heavyspindle requiring a greater pressure.

From the`ab`ove description, it will be ob-y served that a simplek and 'highly'eliicient spindle is provided,4 which is f Capable 4of handling balanced and ,unbalanced loads, which. is relatively inexpensive to manu` facture, and which can be assembled r'in'fa minimum time and with a minimum effort.

It will ber observed thatthe bolster housing is open at its, upperfe'nd for the 'insertion and removal of'lthe. spindlebolster,

and for the reception'of a suitable toolby which the socket member 22 is formed' Iin' the inner wallof said housing. Thebase S is provided withfan oil passage 40 connecting the oilwell- 13. with a hollow upright ll, whose upper end is closed by a cap orcover 42. Q It will also be observed that the tubular portion 10 forming the oil Wellfis extended a Asubstantial distance belowthe base 8,a`nd that the bolster 14 is extended tonear the lbottom of said -oil well and is of smaller diameter so as to be laterally movablethere'- in withthe the ball and socket bearing as a center, 'and that the spindleblade isstep'ped in a fixed bearing near thewlower end of the dition under normal Conditions 4of use.

2. In a spindle, in combination, a bolster housingopen `at its upper end and'closed at yits lower end :to form an oil welle-and having its inner wallprovided with aconcavity f forming a 'socket member opening upwardly,

Y l y v 3. In a lspindle, in combination, a bolster housing having 'ajbase4 provided witha lower tubular portioirextended ldownward therefrom to forni an j oil well, ,and having anknpwardly, extended tubular portion open at itsV upper"y end 4and .provided withinit with-a rigidjsocket memberv opening upwardly, a bolster for the spindle blade insertible into-saidhousing through said upi per tubular member and having'itsflower end extendedinto said oil well, .a ball vmember attached lto* said bolster above Athe rigid socket member and co-:operatingwith the. latter. to ,Suspend vthe, bolster within said uppertubulari member by ia fball, andfsoclzet :healthier .Srrnsleefed within Sdfurrr bolster, whereby the`latter is suspended at I i i tubular member above the ballmember and under substantial initial compression to force the ball member into firm Contact with its co-operat-ing rigid socket member, and means (3o-operating with said upper tubular member for retaining said'spring in its initially compressed condition.

4:. In a spindle, in combination, a bolster housing having a base provided with a lower tubular portion extended downward therefrom and closed at itsv lower end to form an oil well., and having an upwardly eX- tended tubular portion having bores of dit ferent diameters with the bore of smaller diameter below the bore of larger diameter and having its inner Wall adj aeent the bore of larger diameter provided with a substantially semi-spherical shaped concavity forming a rigid socket member, a bolster for to the concavity of the latter, a spring in the bore of larger diameter above said ball member and initiallv compressed a substantial amount to hold the ball member in firm Contact with said socket member, and means co-operatinq with the upper tubular member to retain the saidspring in its initially compressed condition.

In testimony whereof, we have signed our names to this specification.
